Parametric equations area under a graph

Click For Summary
SUMMARY

The discussion focuses on calculating the area under the graph defined by the parametric equations x=2sin(t) and y=5sin(2t), specifically for the lemniscate shape formed by these equations. The key point is that the area can be determined by integrating the equations, with the limits of integration being derived from the symmetry of the shape. It is established that only half of the area needs to be calculated due to this symmetry, and the final result is obtained by multiplying the integral by 2.

The two equations are:
x=2sin(t)
y=5sin(2t)

i have to find the area under this graph (lemniscate)

I know how to integrate it and all, but my question is how do i find the limits?

I presume you mean the enclosed area. In any event, the shape is symmetric so you only need half of it (and multiply the result by 2). If you plot the funtion and look at the values of x(t) & y(t) the limits of integration should become clear.
